How to Select a Filter for Electroplating
Author: Robby
The selection of filter for electroplating needs to consider the following factors:
1. Filtration precision
Requirements: Select the filter with appropriate precision according to the size of impurity particles in plating solution, usually between 1-25 microns.
Choice: High precision filtration can improve the quality of plating layer, but may increase the cost.
2. Flow rate
Requirements: Determine the flow rate according to the volume of the plating tank and process requirements to ensure that the filter can complete the cycle within the specified time.
Selection: The flow rate should match the volume of the plating tank, usually 2-4 cycles per hour.
3. Material
Requirements: The material of the filter should be corrosion-resistant, commonly used materials include PP, PVDF, stainless steel and so on.
Selection: according to the nature of the plating solution to choose the appropriate corrosion-resistant materials.
4. Filtration media
Requirements: commonly used filter element, filter bag, filter cloth, etc., need to be selected according to the filtration precision and flow rate.
Selection: Filter element is suitable for high-precision filtration, filter bag and filter cloth are suitable for large flow and low-precision filtration.
5. Operating pressure
Requirement: The filter needs to operate under specific pressure, too high or too low will affect the effect.
Choice: Ensure that the filter can work stably within the pressure range required by the process.
6. Degree of automation
Requirements: Select manual, semi-automatic or fully automatic filter according to production requirements.
Choice: Full-automatic filters are efficient but costly; manual and semi-automatic are suitable for small-scale production.
7. Maintenance and cleaning
Requirements: the filter needs to be easy to maintain and clean, reduce downtime.
Choice: choose simple structure, easy to disassemble and clean the model.
8. cost
Requirements: comprehensive consideration of the equipment purchase, operation and maintenance costs.
Choice: under the premise of meeting process requirements, choose cost-effective equipment.
9 brand and service
Requirements: Choose famous brands to ensure after-sales service and technical support.
Choice: Give priority to brands with good reputation and perfect after-sales service.
10. Environmental factors
Requirements: Consider the influence of temperature and humidity of the working environment on the equipment.
Option：Ensure that the filter can run stably in a specific environment.
Summarise
When selecting the model, we need to consider the filtration precision, flow rate, material, filter medium, operating pressure, automation degree, maintenance, cost, brand and environment, etc. to ensure that the equipment meets the requirements of the electroplating process and has a good price-performance ratio.
